PETER SGHIFFLER, OF AACHEN, GERMANY, ASSIGNOR TO MATI-IIAS SCI-IIFFLER,OF AAGHEN, GERMANY.

PILE-PLANKING OF ROLLED FIGURED IRON.

To all whom it may concern:

Be it known that I, PETER SCI-IIFFLER, engineer, a subject of the Kingof Prussia, residing at No. 10 Stephanstrasse, Aachen, in the Kingdom ofPrussia, Empire of Germany, have invented certain new and usefulImprovements in Pile-Planking of Rolled Figured Iron; and I do herebycleclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichitappert-ains to make and use the same.

The present invention relates to a pileplanking made of rolled iron,which on account of the scalariform arrangement of the planks proves, inspite of a small quantity of iron being used, of the greatest efficiencyagainst flexure and so enables a compulsory, tight guiding of theplanks. This is attained in such a way as to provide the stemends oftheplanks on opposite sides with a pair of noses which are rolled to them.

Figure l of the annexed drawing represents a top view of such apile-planking, in which the wall is made of rolled figured iron thesections of which are exactly like each other, Fig. 2 is a top view of apile-planking formed of iron of two different sections, Fig. 3 shows arepresentation-form wit-h one plank of normal Z section.

The object of the invention consists in that the stem-ends of the rollediron used in the form according to Figs. 1 and 2 are provided with pairsof clips or noses s, 1' being rolled to the stem and arranged onopposite sides of the same. These pairs of noses, a certain number ofwhich have bent edges, form after the combination of the planks, ascalariform pile-planking with hollow spaces which in turn formbipartite quadrilateral tubes, whereby the planks are guidedcompulsorily, so that actually one plank may he slid into the adjacentone, but prevented from turning around the same. The hollow inner partof these tubes may be filled up in the usual way with stoppingSpecification of Letters Patent.

or tightening stuif. In the form according to Fig. 8, the same as inFig. 2, two different sections are necessary. In this case, however,only one iron must be provided with a pair of noses, while the other oneconsists of a plain normal Z-iron. Then no hollow spaces are obtained,but also here a compulsory guide is at hand.

Having thus described my invention, what I claim is 1. In a metal sheetpiling comprising detachable planking units, the combination with aseries of angularly disposed bars, each bar being provided withinterlocking means for holding another bar in angular relation thereto,of sockets carried by one of said bars, said sockets comprisingangularly disposed extensions projecting from the planking unit, ashoulder upon one of the said extensions said shoulder being bentinwardly with relation to the extensions, heads carried by one of saidbars, and adapted to be inserted in said sockets, said head comprisingan angular extension extending from the planking unit and adapted to fitbetween the angular extension and the shoulder of the socket, whereby tolock the units together.

2. Pileplanking of rolled iron consisting of rolled sectionsscalariformly slid into one another, said sections having for thepurpose of guiding, at their ends on opposite sides pairs of nosesrolled to them, said noses being partly provided with bent edges,forming on the uniting of the planks hollow spaces of the shape ofbipartite, quadrilateral tubes, said tubes producing the compulsoryguiding of the planks.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PETER SCI-IIFFLER.
